Introduction

Its 3011 and the world is back to square one. Its been quite some time since the wipe out

of our civilization and with that has departed any form of knowledge whatsoever. Science is

on a rise and the new breed of human beings is far from re-discovering the present day

conventional sources of energy. The only solution to their energy crisis is that of using

stored potential energy. Put yourself in their shoes and create a machine working solely

using stored mechanical energy.

Task

Teams must build a machine that works purely on the principle of stored mechanical

potential energy. The system should be able to contain the maximum number of table

tennis balls, take it to a given area, drop them in the specified zone and then come back to

the start zone.

Arena Specifications

1. Arena consists of three zones(refer fig 5):a. The start zoneb. The central zonec. The drop zone

2. The start zone is separated from the central zone by a line called as starting line(refer fig5).

3. Dimensions of the start zone will be 300 mm x 300 mm.4. The central zone has a length of1500 mm and is a normal plywood track.5. The area behind the drop line (shown in the figure) is the drop zone. It has a length of

300 mm.

6. The width of the arena will be 940 mm.7. The drop zone will be of dimensions 340 mm x 940 mm and will have a uniform slope of

angle 10o.

Central Zone

The zone would consist of lines parallel to the length of1500mm equidistant fromeach other as shown in figure 1.

All the lines in the arena thickness of the lines would be 10 mm. The lines would be at a distance of150 mm from each other. The lines would represent the zones in which the machine starts to drop the balls.

the machine will be referred to the mechanical mechanism which is used to transportor contain the balls and,

the system will be referred to the machine along with the balls.

Machine Specifications

1. Before the start of the run, the system should fit in a box of dimensions 250 mm x 250mm x 500 mm.

2. The balls will be standard size table tennis balls ofdiameter 40mm.3. The system should be triggered by a single action (pushing a button, cutting a string,

etc.).

4. Touching the system during the run is not allowed.5.

The system should work using only stored potential energy. Use of batteries or any othersource of electrical or chemical energy is not allowed.

6. No part of the machine should separate out during the run.Competition Rules

1. Each participating team will be given two runs.2. At the start of the run, teams would be given a maximum of 2 minutes to setup their bot

on the arena and also insert the balls in to their machine. After these 2 minutes, the

runtime will start.

3. During every run, the team must place its system on the start zone.4. The team will be given a maximum of 3 minutes to complete the task.

where,

T= the total time taken to complete the task in secondsb= 50, if the machine starts to launch the balls in the red zone

10, if the machine starts to launch the balls in the green zone

(Please refer to figure 5 for knowing more about the red, green and yellow zones.)

Eligibility

All students with a valid identity card of their respective educational institutes are eligible toparticipate.

Team SpecificationA maximum of three members are allowed in a team. Students from different educational

institutes are allowed to make a team.

Certificate Policy:1. The top three teams will be awarded the certificate of excellence.2. All the teams who complete the task and deposit 3 balls would be given certificate of

participation.
